5. Setup & Installation
The installation process involves replacing existing hand grips, routing wiring, and installing an on/off switch. Refer to your snow blower's owner's manual for specific handlebar removal and access procedures.
Installation Steps:
- Prepare the Snow Blower: Ensure the snow blower is turned off, the engine is cool, and the spark plug wire is disconnected to prevent accidental starting. Disconnect the battery if your model has one.
- Remove Old Grips: Carefully remove the existing hand grips from the handlebars. This may require cutting them off or using compressed air to loosen them.
- Prepare Handlebars: Clean the handlebar surfaces where the new grips will be installed. Some installations may require drilling a 1/2 inch hole in the handlebars for wiring passage. Consult the detailed instructions provided with your kit for exact drilling locations.
- Install Heated Grips: Apply a suitable handlebar grip adhesive (not always included, may need to be purchased separately) to the inside of the new heated grips and slide them onto the handlebars. Ensure they are fully seated and oriented correctly. A rubber mallet or a piece of wood and a steel hammer may be used to gently tap them into place. Allow the adhesive to cure as per its instructions.
- Route Wiring Harness: Connect the wiring from the heated grips to the main wiring harness. Carefully route the wiring harness along the snow blower frame, securing it with zip ties to prevent interference with moving parts, levers, or pinch points. Ensure the wiring is protected from heat, sharp edges, and abrasion.
- Install On/Off Switch: Mount the on/off switch in a convenient and accessible location on the snow blower's control panel or handlebar, as specified by the kit's instructions. Connect the switch to the wiring harness.
- Connect to Power: Connect the main wiring harness to the snow blower's electrical system as directed by the kit's instructions. This typically involves connecting to a designated power source on the engine or control panel.
- Test Functionality: Reconnect the spark plug wire and battery (if disconnected). Start the snow blower and test the handwarmers by activating the on/off switch. The grips should begin to warm up.
- Final Inspection: Turn off the snow blower. Double-check all connections, wiring routes, and mounting points to ensure everything is secure and free from potential hazards.
6. Operation
Once installed, operating the Ariens Handwarmer Kit is straightforward:
- Start your snow blower as per its operating manual.
- Locate the on/off switch for the handwarmers.
- Flip the switch to the 'ON' position to activate the heating elements in the grips. The grips will begin to warm up, providing comfort during cold weather operation.
- Flip the switch to the 'OFF' position when handwarmers are no longer desired or when turning off the snow blower.
Note:
- The handwarmers are designed to provide a comfortable level of heat. They may get quite warm, especially in milder temperatures.
- Always turn off the handwarmers when the snow blower is not in use to conserve power and prevent unnecessary wear.
7. Maintenance
The Ariens Handwarmer Kit requires minimal maintenance. Regular inspection is key to ensuring continued performance and safety.
- Regular Inspection: Periodically inspect the heated grips, wiring harness, and switch for any signs of wear, damage, fraying, or loose connections.
- Cleaning: Keep the grips and switch clean from dirt, snow, and debris. Use a damp cloth for cleaning; avoid harsh chemicals or abrasive cleaners.
- Wiring Security: Ensure all wiring remains securely fastened and routed away from moving parts or heat sources. Replace any damaged zip ties.
- Grip Adhesion: Check that the grips remain firmly attached to the handlebars. If they become loose, re-secure them with appropriate adhesive.
- Storage: When storing the snow blower for extended periods, ensure the handwarmers are turned off.
